' HEAD-GATE. I

Specification of Lette Patent. Patented Nov/22,1910.

Application filed June 4, 1910, Serial No. 565,005.

To all whom it may concern:

Be it known that I, JOHN H. Bnr'ronri, a citizen of the United States, residing at tain new and useful. Improvements in Head- Gates; and I do declare the following to be a full, clear, and exact description of theinvention, such as Will enableothers skilled in the art to which. it appertains to makeand' use the same, reference being had to the ace companying drawings, and to the letters and figures of reference marked thereon, Which My invention relates, generally speaking, to improvements in-head gates, adapted to controlthe'fiow of water from an irrigating ditch on canal toa lateral or branch ditch termined quantity of water. This gate be-. longs to that class of gates Which are'adaptcannot-be opened wider'than a predetermined limit, whereby the consumer is pro-- vented vfrom using .niore Waterthan he is entitled to. Where these gates are em ployed, there is a ditch rider or superintendent who adjusts the gateand secures it in such a manner that the consumer cannot use-more Water than a'p'redetermined quantity for Whichhe has agreed to pay.

in my improved construction the stem ot" the gate is equipped with a vertically adjustable block into which is] threaded on one wh ch is pivotally connected a slotted arm or link which after the set bolt is tightened to secure the block in-place onthe stem, is adjusted so that its slot shalL register with the eye bolt also carried. by the block. The hasp of a padlock is then passed throngh the opening in the link and also the eye. of the bolt, after'which the ha'sp is inserted in the lock and secured against removal except by a person holding the .key to the lock. When 1 this block is thus secured, it forms a stem farther thanthestop. will allow, In

the stop engages-a crossbar at the; top of I the head. gate frame, the gate is open to which the consumer is entitled, topass' through, but no more. Provision -isf zalsomade whereby the "link attached I to thead-fl ering the gate. 111- my improved construction 1 'preferto 35 ihe collar and the inner extremityof the corof a bolt riveted to the top of the frame, the

link and bolt-being secured together by passing the hasp ofa padlock through the opening ofthe link and the eye of the bolt. so

In, this event the gate is 'prevented from being opened farther than the stop will allow, While at the same time it cannot bev closed-exceptby a person holding the key to the loclnf i It sometimes happens that it-is important to prevent the consumer'from closing the gate, since if this is done the accumulation oflwaterin the ditch .or'canal may result in In my improved construction the stem ofthe head gate is toothed or'notched on one side and a lever isfulcrumed on the frame this purpose, the vertical manipulation of 9 the head gatemay be quickly and easily aecompllshcd, .thus gwlng an advantage in this respect over a nut tor raising and low-' employ a corrugated iron pipe or conduit "WlUCl'l is connected withthehead gate frame by suitable means. As shown in the-drawmg, the headgate frame on the CHIIZIl-SldB'iS provided with a collar wluchis inclined 1n- 9o wardly as it extends rearWardly,I the said collar being equ1pped "w1th lnteriorly proecti-ng eyes or apertured lugs. The heads of the bolts are connected with these lugs, the bolts extending rearwardly and passing through eyes or apertured lugs With which the condult is provided. The'headsof-the boltsin addition to being anchored bythe apcrtured lugs, are further secured in place by a body of cement which is placedhetween 'rugated pipe or conduit. stop to prevenhthenpward movement ofth'e: i

Having briefly outlined my improved cohit struction, I illproceedbodescribethesame i 10 5 in detail, reference--heing made to the ac- "c'om-pany-ing drawing, in which is illustrated an embodiment thereof, a In this drawingzFigurel-i's-afront View Under these circumstances the 70 ga teis locked to prevent both opening and closing, a

gate f1 'a"rne, t-h'estem and the locking devices, illustrating the manner of locking the gate to prevent closing. Fig. 4; is a sectional de-* tail view of the locking device mounted on the stem of "'the' head gate, the parts being shownon a larger scale.

The same reference characters indicate the samepartsm all the views.

Let the numeral 5 designate the head gate.

frame consisting of upright bars 6 having "grooved ways adapted to receive the opposite edges ofahe'ad gate 7, which is adapted p to close an opening '8 either partially or wholly, through which the 'water'fiows from the canal to the lateral, first passing through the conduit or pipe section connected with -.-.the frame ashereinafter.described in detail.

The stem!) is secured to .the gate in any suitable mannerJ-as by rivets or other suit.-

able fasteningdei'fices1 0. This stem passes through arr-opening 11. formed inthe top .bar 13 of the head gate frame and protrudes above the same as shown at 12.

-\lounted on the stem below the cross bar 13'ofthe head gate frame is ablock -14: f;vhich is adjustable by means of a set bolt '15, fWhOSQ lnner extremity" is pointed. as shown at 16 to set bolt. To the outer extremity of-the set bolt is pivotally connected a link 20 which' enter recesses 17 with which one side of the stem is provided. The block 14 is reinforced as-shown at. 18 and interiorlythreaded to receive the setbolt '15. y

Made fast to the block 0r,stop,,18 is an eye 19,-which is preferably locatdbelow the when turned downwardly, may be caused to register with thejeye 19. .Then by locking thelink to the eye 19 byimeans'ofapadlock 4, the stem cannot be moved upwarol-yfan' therthan is-desire d in order toallow the requisite quantity of water to pass through the gate. Now if; itis desired to lock the gate against closin as well as against opening, the block' 14: 1s first properly adjusted to permit the required; opening movement. The gate is then raised'un'til this'block on the stem strikesthe cross-bar13, afterwhich the linkis' thrown to'the'position shown in closing as well as against opening.

The rear surface oi: the head gate frame 15 provided Wll'h 'a collar informing an in- -Fig. '3, whereby. the-gate is locked against wardly flared rearwardly extending member.

The inner surface of this collar is equipped with apertured lugs 23, which form an anchoragefor the heads of the bolts Eat, the

" threaded I extremities of the bolts passing 'filled' .with'cement or concrete 27, whereby the'heads of the bolts are completely bur-led.

through apertured lugs or eyes 25, seeuredto a corrugated conduit member 26. The space between-the collar 21 and thecondult 26, 1s

' The lifting movement of the gate. is accomplished through the instr'umental'ity of a. lever 28 fulcrumed as shown at 29 onan extension 30, with which one of the side members -5 of the head gate frame is provided. Between the fulcrum and the ex tremi-ty of the lever, the latter crosses the portion 12 of the head gate stem above the cross bar 13 and a spring-actuated dog 31 34 will engage a notch 32 and support the gate to the height raised, by this movement of the lever. If afurther opening move ment of the gate is required, the dog 81 is'.

Withdrawn from its notch, and the handle extremity of the lever lowered and the dog 31 allowcd'to engage a lower'notch, after which the lifting operation is repeated.

This may be done as often-as necessary in order to give the gate the required opening movement. This movement, however, is limited by the stop block 14, which it is assumed is' properly adjusted and looked as heretofore explained.

. Having thus described my invention, what I claim is:

l. The combination with a head gate having a stem, of a stop block slidably mounted on the stem, a set bolt threaded in the block for securing the block in place on the stem, and means for lockin the set bolt against movement, substantial y as described.

2. The combination with a head gate, having a stem, a frame in which the head gate is'movable, the frame having a cross bar provided with anopenmg through which the .stem of the gate passes, a stop block mounted on the stem below the cross bar of the frame, a set bolt threaded in the block, and means for'locking the set bolt against turning, substantially as described.-

The combination with a frame, a head gate movable in the frame, and havin' a. stem'passing through an opening forme in ,a cross bar with which the frame is provided, a sto block slidably mounted on the stem be ow the cross bar, a set bolt threaded in the sto inner extremity pointed to enter recesses with which thestem is provided, a link block and having its pivotally connected with the set bolt, and

means coiiperating' with the link for locking the set bolt against turning movement,

substantially as described.
